New Orleans police on Tuesday jailed a second suspect in the recent slaying of 17-year-old Aaron Scott, authorities said.

Charles Reed, also 17, is accused of fatally shooting Scott, his classmate, with a handgun in the 4700 block of Babylon Street about 5 p.m. Saturday. According to information from officials and an arrest warrant application filed in Criminal District Court, Reed allegedly got the gun from someone also involved in the murder. On Monday, police arrested 16-year-old Michael Tobias in connection with Scott's killing.

Both Reed and Tobias were booked with first-degree murder and attempted first-degree murder. Reed on Tuesday remained in Orleans Parish Prison, while Tobias stayed at the city's juvenile detention center. Neither can post bail because they are suspects in a first-degree murder case.

Officials have said that an argument broke out shortly before the killing. The police report alleges that Reed approached Scott and shot him in front of several of their classmates. He then fired several bullets at another person close to Scott.

The 5-foot-5, 120-pound Reed allegedly told the witnesses he shot Scott before running off with the handgun. Someone called 911, but Scott died before paramedics could arrive to help, police said.

Several witnesses reportedly told investigators they recognized Reed because he attended the same school with them for about nine months. Police did not specify which school Reed attends.

The witnesses knew the suspect's first name was Charles and his nickname was "Scooter." They also knew he had been arrested in connection to a burglary in Houston and that he lived with his sister, according to the arrest warrant application.

They also said that Reed told them he got the gun "from another person involved in the murder," who appears to be Tobias. Police spokesman officer Janssen Valencia on Tuesday said investigators did not inform him that they were searching for any more suspects.

Detectives telephoned Houston police, who confirmed Reed's burglary arrest. They then called Reed's sister. She confirmed that her brother's nickname was "Scooter" and provided their mother's name and a former address, information the detectives verified with Houston police documents, according to the warrant application.

The warrant application notes, however, that the detectives could not find Reed's photographs on file with any Louisiana or Texas law enforcement agencies. They also could not find any school photos or state identification cards of Reed.

A magistrate judge nonetheless signed off on Reed's arrest warrant at 10:20 p.m. Monday, according to the document. Reed, who lives in the 6200 block of Chef Menteur Highway, surrendered at police headquarters less than an hour later and was processed into the jail about 4 a.m. Tuesday.

Reed and Tobias can only receive a life sentence if they are convicted of first-degree murder because the U.S. Supreme Court in 2005 banned the death penalty for anyone younger than 18.
